Detailed explanation-1: -The researchers used a rigorously controlled experiment with a placebo condition to avoid the effect of confounding (extraneous) variables. The study is able to establish a cause-and-effect relationship; however, it is a reductionist approach to understanding memory.
Detailed explanation-2: -As summarized in Figure 1, acetylcholine may enhance the encoding of memory by enhancing the influence of feedforward afferent input to the cortex, making cortical circuits respond to features of sensory stimuli, while decreasing excitatory feedback activity mediating retrieval.
Detailed explanation-3: -Glutamate is the most abundant excitatory neurotransmitter released by nerve cells in your brain. It plays a major role in learning and memory.
Detailed explanation-4: -Acetylcholine (ACh) is an important neurotransmitter that plays a role in brain functions, such as memory, and body functions, such as muscle contractions to move your muscles. Low levels of acetylcholine are associated with memory issues and muscle disorders.
